Object duplicating while moving it? (lwjgl)

I’m using lwjgl and I have an object that I’m moving by using glTranslatef. It has worked exactly how it is supposed to so far but suddenly it started to draw the object twice. I don’t understant what could cause this. I’m 100% sure that I am not having other objects that could cause this. I’m not giving any code here because I think this happens because of some weird opengl setup thing or something that I’m not even aware of. Please give me some suggestions? :persecutioncomplex:
